    of stakeholders relative to choices of wastewater system scale Up to 10 case studies covering seven specific topics that have received little or no attention in the literature to date will be developed The topics that will be addressed include 1 financial benefits of incremental capacity expansion through implementation of decentralized systems 2 impacts of wastewater system choices on community growth development and autonomy 3 hydrologic impacts of wastewater systems 4 implications for fairness and equity within communities 5 how communities evaluate reliability vulnerability and resilience of wastewater systems 6 the role of wastewater facility decision making processes in developing positive image and trust in stakeholder public relationships and 7 the value of decentralized systems to sanitation utilities that already manage large centralized systems The investigations will seek both quantitative and qualitative economic and social process information The research products will include case study synopses and integration of the case study findings into a research report Rocky Mountain Institute is now developing for the U S Environmental Protection Agency That report is a catalog of all issues with potential economic implications that do or should arise as communities choose between centralized or decentralized options for wastewater systems or that follow

    for onsite wastewater treatment systems However estimation of explicitly defined risks associated with such rules has not been accomplished due primarily to the lack of a standardized method for integrating disparate risks into a comprehensive approach that can be applied at various sites and geographical scales This project will develop a general risk based framework for integrating the results from four different types of assessments into a single cohesive risk

    data resource will provide some insight into where potential customers are now on issues of the acceptance of distributed technology options and innovative system management options but also will provide initial information about how customers might be moved to be more receptive to such options in the future Prior research and analysis on the subject of market penetration paths for decentralized wastewater treatment systems points to an uncertain future While technology advances have been made and customer interest has started to pick up there is still enough uncertainty in terms of demonstrable technology performance customer and regulatory acceptance the impact of other interest group activities and agendas and other issues that the rate of increase at which decentralized wastewater treatment technologies DWTT cluster systems and innovative wastewater system management options will be adopted and the timeline and market segments along which these options will be implemented is a very open question While there are market scenarios that point to the possibility of relatively widespread adoption of DWTT within a reasonable time frame the confluence of forces necessary to yield this outcome has not yet come together One of the real unknowns in understanding both the likelihood of this outcome and

    Town of Tisbury has developed a Community Wastewater Management Plan CWMP to provide for comprehensive management of approximately 2 400 septic systems in the Town NDWRCDP support has been provided to the Town to assist them in performing an environmental risk assessment of Tisbury s waterbodies and groundwater and to all for the development of a risk based management program for decentralized wastewater systems The project will include a characterization

    and maintenance Typically maintenance and inspections were left to the individual homeowner and failures were frequent Just as changing or not changing the oil can make a difference in the life of an automobile routine pump outs and repairs can improve the functioning and life expectancy of the septic system The newer technologies using mechanical pumps and floats smaller filter units and similar devices will require even greater oversight The idea that a private or public entity can hire qualified staff and perform these functions cost effectively for hundreds or thousands of systems in a geographic area is a good one and a potential new business venture Finally with the emergence of watershed planning and an increasingly sophisticated understanding of ecosystem conditions the potential to target specific technologies in specific areas with attendant cost savings and enhanced environmental protection is coming to be understood Ultimately engineers should be able to assess the ecological conditions in the area site more expensive advanced systems in zones where needed and develop monitoring programs to track impacts of system performance on the environment The fact that there is a centralized management entity for this work could give regulators the confidence to allow for such targeting flexibility Within a watershed remediation of failing on site systems through programs of advanced technology where needed and professional management may obviate the need for expensive sewer extensions or treatment plant upgrades to improve or maintain water quality The purpose of this study has been to explore the short and long term opportunities for advanced on site and cluster system technologies and management across the country Two research projects were undertaken First a database was assembled with information on each of the counties in the U S including various risk related factors as percentage of undeveloped soils with hydraulic
